Scuderia Ferrari SF15-T

[Giblet]

Despite the fact it is internal, is not the internal bodywork of the SF15-T in the exclusion zone where such devices are not allowed?

what appendage are you talking about?

I wonder if these winglets exist as speculated and if so are they legal? If a team was to slap a bunch of winglets on the outside of the sidepods it would not be ok, so why is it OK on the inside? IIRC the rules involve measurements from the center line and floor which should include bodywork what's purpose is 'cooling' even though they have a cascade wing in there?

The number of elemnets (again if correct) seem like a mid cascade wing, where the other teams have one in the front and one in the rear only

Pretty sure there is a line in the rules which stops winglets like pre 2009 that days something about being visible, these winglets on the radiator are not visible because of bodywork.

guess this confirms you dont need a anorectic body to be competitive in f1, a latina body is also an option, that rb compared to a chubby ferrari

true, and the sauber is doing well, too.

interestingly though, the RedBull can't get skinnier, and seems at the max of its performance.
Meanwhile, the Ferrari probably CAN get skinnier by quite a measure, AND doesn't seem it's at the max of their performance.

WTF?

Still I'm not sure RBR didn't find a different way to mess it up. One proven way to do this is having rigidity Problems somewhere in the Chassis/ Suspension. This often manifests itself in unpredictable over/understeer also in slow Corners. Looking at the behaviour of the Bulls I think I have seen signs of that. So the tighter Rear End might still be beneficial but it could be overshadowed/nullified by other issues.
On the other hand the F15 Sidepods are not that chubby in 3D. They have a totally different shape tapering inward in the upper half and thereby allowing airflow on the upper end to move inward more freely than the sidepods which have their widest part in the upper half.

"3.8.4
Any vertical cross section of bodywork normal to the car centre line situated in the volumes defined below must form one tangent continuous curve on its external surface. This tangent continuous curve may not contain any radius less than 75mm"

So, no restrictions on the inside of the pods. Otherwise, every mechanical component in contact with air (therefore "bodywork" by definition) would be deemed illegal.

[Giblet]

Thanks for clearing that up, cheers.

One question, looking at the drawing of engine at the bottom picture it seems that Ferrari retained tubular exhaust piping. Is that right?

But since the tuned mass damper... never mind!
Where I meant to be really annoying is in that Giblet is right, what is "internal" anyways? Last time I checked the radiator could be largely seen from outside the car, and all cars are, topologically, some sort of triple doughnut anyways. The insides of the sidepods have to be "external" by definition to cool things using ambient air.
Without a proper definition of external, one could have any intricate shape (read illegal as per the radius rule above) made legal by sticking another "legal" element further away from the center of the car. The second element becoming the "external" one and thus making the intricate one "internal" and legal. Turning vanes outside the turning vanes anyone? How many opening can a sidepod have and still be a sidepod?
An interesting can of worms!
I know I am nitpicking, but interpreting that rule literally, one cannot have an ultrashort sidepod with its rear exit still inside the "volumes defined below", and I am quite sure that that was never the spirit of the rule.
Good catch, gents!

This time there's no room for interpretation.

The "vertical cross section" (cited earlier) cuts the car transversally, thus drawing many concentric profiles: the most external (=on the outside) one is subject to the 75mm rule.

The so formed radiator duct cross section would be consequentely seen as a profile contained inside the more external "actual" bodywork cross section.

I other words: if you see two concentric circumferences, would you have any doubt about whichone is on the inside and which one on the outside (therefore "external")?

[bhall II]

Just to muddy the waters a little bit...

1.4 Bodywork :
All entirely sprung parts of the car in contact with the external air stream, except cameras, camera housings and the parts definitely associated with the mechanical functioning of the engine, transmission and running gear. Airboxes, radiators and engine exhausts are considered to be part of the bodywork.

[hollus]

I see that interpretation, variante. But is it watertight? Do these external surfaces have to extend, longitudinally, from the front end to the back end of the legality box? Would a 50 cm long sidepod, complete with entry and exit, be legal? Or would something like ribs be legal? If the external surface doesn't have to extend out of the box (maybe it has to and that is that is the trick in the wording), why is external defined by vertical projections and not by horizontal projections? Wings have a similar radius rule, and yet they have pointy ends and lots of words to implicitly define "inside"...
I guess I am missing some small text in the rules, too tired to check it now, I might find the time later. I probably should stop fishing for tricks until then.

Ferrari SF15-T - oil tank position



On their 2014 car, Ferrari unusually placed the oil tank at the rear of the engine inside the gearbox casing (see inset). What have they done for 2015?

On the SF15-T the oil tank is back in the conventional position – in front of the engine (1). However, the intercooler has been kept in the same place as last year (2). The exhausts (3), meanwhile, have been completely revised in order to maintain the best compromise between engine power and heat exchange feed to the MGU-H.
